TYPE-WRITING MACHINE.

Original application filed August 22, 1910, Serial No. 578,457, Di'vided and this application filed August I 18, 1911. Serial No. 644,724.

To all whom it may concern:

Be it known that 1, CHARLES H. VoenL, a British subject, residing in Vancouver, in the county of Vancouver, Province of British Columbia, Dominion of Canada, have invented certain new and useful Improvements in Type-Vtriting Machines, of which the following is a specification.

This invention relates to the operating mechanism of type-writing machines, and

' the object of the invention is to provideimproved, simple, and efficient means for operating the keys by a very light touch.

This application is adivisio'n of my application No. 578357, filed August 22, 1910. In carrying out my invention, a rock shaft rockedby one of the keys imparts a partial stroke to a universal bar by means of a dog on said shaft engaging on a pin on the bar. Said partial stroke causes the bar to turn a toothed wheel for the extent of one tooth. The wheel is in an electric circuit and a shoe is thereby caused to engage and disengage with one of the teeth, whereby the circuit is closed and opened, the closing-of the circuit causinga magnet therein to draw the universal bar to complete its stroke. During the completed stroke of the universal bar it engages said dog by a pin to rock the shaft, which operates the corresponding type bar, by means of a link and arms, and simultaneously pulls a bell crank to actuate anescapement to feed the carriage. Lost motion is provided'on said bell crank and one of said arms-to render'the escapement and type ineffective during the partial I movement of the universal bar.

bar; the other broken away.

The drawing is a perspective, which diagrammatically illustrates my invention, certain parts being omitted, and others being In this view, I show. only the parts necessary to actuate the single type type bars and their actuating parts being omitted for the sake of clea rn'ess. Upon a base plate A is attached a keyboard 1, in which key 2 is mounted, having a stem 3 which extends downwardl and is attached to an arm 4 which enables tfie key to rock a rock shaft 5 which extends from front to rear of the machine; the rear end of said rock shaft being mounted in a back plate 6,

The rock shaft 5 carries a do close to the face of a universal %ar 9, which is mounted to slide transverselyto said rock shaft from side to side of the machine on guide pins 10. The dog 8 normally inclines toward the left, sothat it rocks toward the right by the depression of a key. When the key 2 is depressed, the dog 8 swings slightly toward the right, and gives the uni versal bar 9 a partial movement by engaging a pin 11 on the bar. This partial movement is sufiicient to enable an extension 13 at the lower edge of the universal bar torotate a ratchet wheel 1 1 for the extent of a single tooth. The ratchet wheel 14 is insulated, and is held against a backward rotation by an insulated detent pawl 15. The ratchet wheel is of conducting material, and has a brush 16 constantly in contact with it, said brush being in a circuit 17' 'with a battery 18. vided an electro-magnet. 19, which is connecte'd by conductor 20 of the circuit with a contact shoe 21, which is insulated and.

fixed with its end projecting into the path of the teeth of the ratchet wheel. 'From this arrangement, when the wheelis rotated one of-the teethv of the ratchet wheel strikes and passes the contact shoe 21, which closes the Patented Dec. 2, 1913.

8, disposed In this circuit there is procircuit through the eleetro-magnet or solenoid 19,. and then immediately breaks it,

causlng themagnet 19 to attract an. arma-" ture 22, attached to or forming a part of the adjacentend of the univer'sal'bar. this way the magnet draws the universal bar over, giving it its completed stroke, and

upon the immediate breaking of'the circuit,

the unlversal bar is I returned by spring 23. Whenever the dog 8 is actuated it is swung into the path of a second pin 12 on the universalbar so that when the universal bar is I given its completed stroke'by the magnet 19,

the pin 12 strikes the dog-8 and rocks the shaft 5 in the same direction as the key did.

Rock shaft 5 is provided with an arm 31, which has'a slot 32 receiving a pin 33 projecting from a link 3 1 which extends upwardly and connects with a rocker arm 35 fixed on a wrist 36, said wrist being rota tably supported upon a hanger ring or plate 37 and carrying a type bar 38 which is normally the position indicated in dotted lines. The free end of this type bar 38 is provided with a type. 39, and when the link 34 is pulled down, this type 39 describes a curved line 40 which brings it to the striking point 26.

The universal bar 9 is connected by a pin 27 with a bell crank 28 through a slot 29,

so that the completedstroke of the universal bar 9 pulls the bell crank 28 and link 30 connected .thereto to actuate an escapement device andfeed the carriage, not

* shown in the-drawing. It will be seen that tion with a type bar and a key, of a rock shaft extending from front to rear of the machine and rocked by the key, a universal ba'r reciprocating from sideto side of the machine and transversely of said shaft, a dog on said shaft actuating said universal bar to give it a partial stroke, an electric, 'clrcultc osed byisaid partial stroke, a magnet in said circuit for drawing said universal bar to complete its stroke and connection between said rock shaft and 315 erate it; said connection having lost motion t9 renderthe bar ineffective during the partlal stroke of the universal bar, and the completed stroke of said bar actuating said dog I to operate the type bar by means of said connection.
